Unit Eight: Work & Energy

Work = w = any change in energy = ∆E
w = force x distance = N x m
Units = Joules


The Law of Conservation of Energy: energy cannot be created nor destroyed, it only changes form.

Work Energy Thereom  = total initial energy = total energy out

Potential Energy (gravitational) = PEg = Ug = total energy = w = f x d = mg x h.

Potential Energy is the energy possessed by a body by virtue of its position relative to others.

Kinetic Energy = KE = K = ½mv²



 Here is a video of my sister "working". XD
